Asphalt is a popular choice repairing and maintaining residential driveways. It’s durable, easy to repair, and relatively affordable. But like all things, over time, your asphalt driveway will start to show signs of wear and tear. And when that happens, you’ll need to decide whether to overlay or replace it. So how much does it cost to overlay an asphalt driveway?
CAM Service & Repairs LLC. will give you some helpful information about asphalt overlay.
What Is Asphalt Overlay?
Asphalt overlay is a process in which a new layer of asphalt is laid over an existing one. This is usually done when the existing asphalt starts to deteriorate, but it can also be used to improve the look of your driveway or repair damage.
There are two main types of asphalt overlay, partial and full-depth. Partial overlays are thinner and only cover the top layer of asphalt, while full-depth overlays are thicker and go down to the base. The type of overlay you need will depend on the condition of your existing driveway.
The Five Factors That Determine the Cost of an Asphalt Overlay
The condition, type, and elevation of the existing pavement determine the surface preparation for an overlay project. The existing pavement should be structurally sound, level, clean, and capable of adhering to the overlay. The old pavement is generally repaired, leveled, cleaned, and then covered with a binding substance to satisfy these criteria.
The prominent factor is the type of asphalt you choose. There are two main types of asphalt used in overlays: hot mix and cold mix.
The hot mix is the more durable and long-lasting option, while the cold mix is a less expensive alternative installed in colder weather.
The subgrade is the layer of soil beneath the pavement. The subgrade must be stable and free of any organic materials for an overlay to succeed. If the subgrade is not adequately prepared, it can cause problems with drainage and lead to cracking or unevenness in the overlay. The cost of subgrade preparation will vary depending on the condition of the existing subgrade.
It is the most significant factor affecting the price of an asphalt overlay. The larger the area, the more material and labor required, and the cost will increase accordingly. An asphalt overlay project ranges from $6 to $12 per square foot.
Another thing to consider is the existing lot’s elevations. Is there enough space to overlay the property and still have adequate drainage? A minimum of 1 1/2″ asphalt thickness is required; therefore, the pavement must be settled or milled down.
The steeper the grade, or pitch, of a driveway, the more asphalt will be used because it will take more to cover the same area. If the parking lot is flat, the amount of milling required to make a solid connection increases. If there is a lot of milling, it may be more cost-effective to remove the current driveway and start from scratch.
Asphalt overlay can be a great way to improve the look and feel of your driveway, parking lot, or roadway. It makes the surface smoother and more even, but it can also increase the lifespan of the asphalt by protecting it from weathering and wear and tear.
